Abstract: ABSTRACT        A vehicle mounted lift device for moving a wheelchair and its occupant to and from the bed of the vehicle includes a mounting apparatus fixed to the bed of the vehicle and a support assembly movably mounted to the mounting apparatus for being pivotally or translationally movable between a storage position and an outwardly extending operating position. The support assembly has a vertically stationary assembly which includes a pair of support posts, a  lead screw mounted to each support post, a motive device for rotating the lead screws and a synchronizing apparatus interconnected so that the lead screws rotate at the same rate.  The vertically stationary assembly also includes a safety flap apparatus to prevent inadvertent movement of the wheelchair from the vehicle through the access opening.          The support assembly also has a vertically movable assembly which includes a coupling post interconnected to each lead screw and a foldable platform assembly pivotally connected between the coupling posts.  As the lead screws are rotated the vertically movable assembly is raised or lowered.  Switches prevent operation of the motive device when the support assembly is not in the operating position and when the vertically movable assembly is fully raised or fully lowered.

Abstract: ABSTRACT OF THE DISCLOSURE           A pneumatic control system for a dynamic pressure wave device connects a source of pressurized gas to the first chamber of the appliance.  When the pressure in the first chamber reaches a first predetermined level, a valve seals the first chamber and connects the source so as to inflate a second chamber about the first.  When the pressure in the second chamber reaches a second predetermined level, a valve permits the first chamber to deflate while con-tinuing to connect the second chamber for inflation.  A seal for the inflated sleeve discontinues the inflation of the sleeve when the pressure therein reaches a third predetermined level.  The sequence of operation of the pneumatic control circuit will cause a suitable dynamic pressure wave appliance to apply a pressure to a human or animal extremity which begins at the most distant end and travels up the extremity in the nature of a pressure wave.

Abstract: Abstract SAW CHAIN USING AN IMPROVED SIDE CUTTER TOOTH           To provide better performance for a saw chain by enhancing the life and performance of side cutter teeth, this invention discloses a novel side cutter tooth which includes a cutter element having either a continuously curved portion attached to the body of the cutter tooth or a substantially straight portion extending outwardly from the body of the tooth. The continuously curved portion or substantially straight portion causes the cutter element to bend substantially at the intersection between the body and the cutter element when the cutter element is exposed to inwardly directed forces which tend to flatten the curved or substantially straight portion out of its half-space into the plane defined by the body of the cutter tooth.  Removal of the complex curve ordinarily used in the center-mounted cutting teeth of saw chain greatly enhances the performance of the cutting teeth, reduces breakage of the teeth, and improves the efficiency of a saw chain using the improved cutting teeth.

Abstract: ABSTRACT A plurality of multiprocessor systems is arranged in a high speed network to allow any processor in one system to communicate with any processor in another system.  The network may be configured as a multi-node dual bi-directional ring having a multiprocessor system at each node.  Packets of information may be passed around the ring in either of two directions and are temporarily stored in buffer memory locations dedicated to a selected destina-tion processor in a selected direction between each successive transfer between neighboring nodes.  The buffer locations are managed so that a node can request an adjacent node to stop transmitting packets if the buffer is becoming full from that direction and request resumption of transmission of packets as the buffer empties.

Abstract: "Apparatus for Detecting In-Band Single Frequency Signaling Tones from FDM channels"                          ABSTRACT   A time-division multiplexed (TDM) signal carrying speech information and in-band single frequency signaling tones is simultaneously applied to a digital band-pass filter and a digital band-elimination filter.  The signaling tone components of the TDM signal are passed through the band-pass filter, while they are eliminated by the band-elimination filter.  First and second digital rectifiers convert the outputs of band-pass and band-elimination filters into first and second single-polarity TDM signals, and integrated by first and second digital integrators to generate first and second integrator outputs having mutually distinguishable digital values.  A digital comparator compares the integrator outputs with each other and generates a TDM comparator output when the first integrator output is greater than the the other by a predetermined amount.  A verifying circuit is provided for sequentially detecting the duration of a series of digital bits in each time slot of the TDM comparator output specified by the location of the channel in which the signaling tone is generated and sequentially verifying that the detected duration exceeds a predetermined duration.
